Abstract

This invention introduces methods and mechanisms of partial integrity protection in mobile systems. A user equipment (UE), comprising: a memory configured to store instructions; and a processor configured to execute the instructions to: receive, from a network device, user plane data having integrity protection; send an error indication indicating an integrity protection error relating to the user plane data; and receive retransmitted user plane data from the network device with a reduced data rate, based on the error indication.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A user equipment (UE), comprising:
 a memory configured to store instructions; and   a processor configured to execute the instructions to:   receive, from a network device, user plane data having integrity protection,   send an error indication indicating an integrity protection error relating to the user plane data, and   receive retransmitted user plane data from the network device with a reduced data rate, based on the error indication.   
     
     
         2 .- 3 . (canceled) 
     
     
         4 . The UE of  claim 1 , wherein the integrity protection error corresponds to a failure of the UE in performing an integrity protection check on the user plane data. 
     
     
         5 .- 7 . (canceled) 
     
     
         8 . The UE of  claim 1 , wherein the integrity protection error relates to capability information of the UE. 
     
     
         9 . The UE of  claim 1 , wherein the processor is further configured to execute the instruction to:
 send a success indication indicating an integrity protection success corresponding to a success of the UE in performing an integrity protection check on the retransmitted user plane data.   
     
     
         10 . The UE of  claim 1 , wherein the processor is further configured to execute the instructions to:
 send a success indication indicating an integrity protection success corresponding to a success of the UE in performing an integrity protection check on the retransmitted user plane data, wherein   the integrity protection error corresponds to a failure of the UE in performing an integrity protection check on the user plane data.   
     
     
         11 . A method comprising:
 receiving, by a user equipment (UE) and from a network device, user plane data having integrity protection;   sending, by the UE, an error indication indicating an integrity protection error relating to the user plane data; and   receiving, by the UE, retransmitted user plane data from the network device with a reduced data rate, based on the error indication.   
     
     
         12 .- 13 . (canceled) 
     
     
         14 . The method of  claim 11 , wherein the integrity protection error corresponds to a failure of the UE in performing an integrity protection check on the user plane data. 
     
     
         15 .- 17 . (canceled) 
     
     
         18 . The method of  claim 11 , wherein the integrity protection error relates to capability information of the UE. 
     
     
         19 . The method of  claim 11 , further comprising:
 sending, by the UE, a success indication indicating an integrity protection success corresponding to a success of the UE in performing an integrity protection check on the retransmitted user plane data.   
     
     
         20 . The method of  claim 11 , further comprising:
 sending, by the UE, a success indication indicating an integrity protection success corresponding to a success of the UE in performing an integrity protection check on the retransmitted user plane data, wherein   the integrity protection error relates to capability information of the UE.   
     
     
         21 .- 30 . (canceled) 
     
     
         31 . A method comprising:
 sending, by a network device and to a user equipment (UE), user plane data having integrity protection;   receiving, by the network device, an error indication indicating an integrity protection error relating to the user plane data; and   sending, by the network device and to the UE, retransmitted user plane data with a reduced data rate, based on the error indication.   
     
     
         32 .- 33 . (canceled) 
     
     
         34 . The method of  claim 31 , wherein the integrity protection error corresponds to a failure of the UE in performing an integrity protection check on the user plane data. 
     
     
         38 . The method of  claim 31 , wherein the integrity protection error relates to capability information of the UE. 
     
     
         39 . The method of  claim 31 , further comprising:
 receiving a success indication indicating an integrity protection success corresponding to a success of the UE in performing an integrity protection check on the retransmitted user plane data.   
     
     
         40 . The method of  claim 31 , further comprising:
 receiving a success indication indicating an integrity protection success corresponding to a success of the UE in performing an integrity protection check on the retransmitted user plane data, wherein   the integrity protection error relates to capability information of the UE.   
     
     
         41 . The UE of  claim 1 , wherein the integrity protection error corresponds to a failure of the UE in performing an integrity protection check on the user plane data and relates to capability information of the UE. 
     
     
         42 . The method of  claim 11 , wherein the integrity protection error corresponds to a failure of the UE in performing an integrity protection check on the user plane data and relates to capability information of the UE. 
     
     
         43 . The method of  claim 11  further comprising:
 sending, by the UE, a success indication indicating an integrity protection success corresponding to a success of the UE in performing an integrity protection check on the retransmitted user plane data, wherein 
 the integrity protection error corresponds to a failure of the UE in performing an integrity protection check on the user plane data. 
 
     
     
         44 . The method of  claim 31 , wherein the integrity protection error corresponds to a failure of the UE in performing an integrity protection check on the user plane data and relates to capability information of the UE. 
     
     
         45 . The method of  claim 31  further comprising:
 receiving a success indication indicating an integrity protection success corresponding to a success of the UE in performing an integrity protection check on the retransmitted user plane data, wherein 
 the integrity protection error corresponds to a failure of the UE in performing an integrity protection check on the user plane data.
